I have the following table in MATLAB:
A=
86 84
45 65
2 42
44 29
MATLAB automatically returns for this table the column names A1 and A2, with A being the set name of the table, for the two columns.
How can I manually change the names of each column?
That can be easily accomplished using the VariableNames parameter of the array2table function (the same is valid for the cell2table function too), as follows:
A = [
86 84
45 65
2 42
44 29
];
T = array2table(A,'VariableNames',{'X' 'Y'})
The output table is:
T =
X Y
__ __
86 84
45 65
2 42
44 29
For an already existing table, you can use the same property on the instance itself in order to change its column names:
A = [
86 84
45 65
2 42
44 29
];
T = array2table(A,'VariableNames',{'X' 'Y'})
T.Properties.VariableNames = {'U' 'V'};
T
Take a look at the outputs:
T =
X Y
__ __
86 84
45 65
2 42
44 29
T =
U V
__ __
86 84
45 65
2 42
44 29
